Finding 3rd battle impossible to get through. All the specialty coding making it too difficult. I.e. death revenge and sleep all moves are not random. Pathetic changes.
Keep at it man! You can do it
I done it with stun revenge epic(spam them and eventually I won).
Hope it work for you too

Techniques that almost always work: Last biter and soulstealer + legendary dreamhunt sleeper
Go with death revenge, stun absorb and knockback front then open up with stun healer then bombers/bursters to either timestrike bloodcravers or 400sec bombers. Once you stunlock the enemy only kill one of them then kill the new monsters that come in. The challenging part is removing the stun resist front.
